Coal Mining in Europe: A Study of Practices in Different Coal Formations and Under Various Economic and Regulatory Conditions Compared with Those in the United States

Description: From Introduction: "The major purpose of this bulletin, as indicated in the preface by Dr. John W. Finch, Director of the Bureau of Mines, is to give a critical review of the coal-mining methods used in the principal producing countries of Europe, to describe the reasons underlying the adoption of these methods, and to contrast them with coal-mining methods employed in the United States."

Comparative Tests of Run-of-Mine and Briquetted Coal on Locomotives

Description: From Introduction: "For purpose of procuring data that could be using in estimating the value of the briquetting process as applied to American fuels, the United States Geological Survey, in cooperation with other interests, began in 1904, at the Louisiana Purchase Exposition, certain experiments involving the production and use of bituminous-coal briquets."

Development of the Fischer-Tropsch Oil-Recycle Process

Description: From Introduction: "This report on the development of the oil-recycle process covers: 1. Review of the work in Germany on the first oil-circulation process. 2. Work by the Bureau of Mines, United States Department of the Interior. (a) Preliminary experiments on a laboratory scale, consisting of orientation tests and bench-scale operation, employing a 1-foot bed of catalyst in a 3-inch diameter vessel. (b) Operation of 2 pilot plants with a 4- or - 8 foot bed of catalyst in 3-inch-diameter reactors. Up to 3 gallons of C2+ hydrocarbons was produced per day in each of these plants. (c) Operation of a barrel-per-day pilot plant with an 8-foot bed of catalyst in an 8-inch-diameter reactor."

Features of Producer-Gas Power-Plant Development in Europe

Description: From Introduction: "Because the limited time available would not permit a careful inspection, much less a detailed study of all the plants visited, the writer has not aimed in this bulletin to present a comprehensive review of producer-gas power-plant development in Europe, or even to give such conclusions as might be drawn from what he saw, but has simply described some interesting features of European practice that attract the attention of even a casual observer."

German Low-Temperature Coal-Tar Industry

Description: Report issued by the U.S. Bureau of Mines discussing a low-temperature coal-tar industry in Germany. As stated in the Purpose and Scope of the Investigation, "the primary purpose of the investigation covered by this report was to determine to what extent the production and use of low-temperature tar in Germany had advanced during the 10-year period prior to the close of the last war" (p. 7). This report includes tables, illustrations, and a photograph.

Hydrogenation of Coal and Tar

Description: From Abstract: "This bulletin traces the development of high-pressure, coal and tar hydrogenation technology, based on intensive review of the pertinent literature. The bulletin was written as a part of the Bureau of Mines research program on synthetic liquid fuels. It covers the history and economics of the process; the chemical aspect of hydrogenation of coal, tar, and middle oil; the engineer aspect of converting coal and tar to liquid fuels, principally gasoline; and the equipment of the process."

Index of Oil-Shale and Shale-Oil Patents, 1946-56: A Supplement to Bulletins 467 and 468: (In Three Parts) [Part 3]. European Patents and Classification

Description: From Introduction: "This part of Bulletin contains 250 European patents that relate to retorting (and distilling underground), refining, and utilization of oil shale and its products. The largest single group, of which the majority was assigned to a single company, relates to fluidized handling shale. The patents are arranged numerically, and alphabetical list of investors and assignees follow them. A classified list of all the patents follows the author index of Part III. Parts I and II were published in 1958."

An Index of Shale-Oil Patents

Description: From Introduction: "Work on this project was begun early in 1944; and the results with respect to shale oil are reported in this Bulletin. Since this bulletin is only an index to this large repository of ideas relating to the the treatment of shale oil, the material is presented in the form of short notices describing the subject material of each patent, which consist of an abridgment of the patent (if British or Australian) or a typical claim in the case of the United States or foreign patents."

International Conference of Mine-Experiment Stations: Pittsburgh, Pennsylvania, U.S.A., September 14-21, 1912.

Description: Report discussing an international conference on mine-experiment stations assembling in Pittsburgh, Pennsylvania. The United States sent invitations to countries that had mine-experiment stations, Great Britain and Canada were the only countries, that did not accept invitation.

Mining Petroleum by Underground Methods: A study of Methods used in France and Germany and Possible Application to Depleted Oil Fields under American Conditions

Description: From Introduction: "That the percentages of extraction of petroleum from the ground may and undoubtedly will be greatly increased in the future by underground mining methods where natural conditions will permit seems logical. The limitations imposed by depth, temperature, and flow of water under high pressure through the sands will be discussed later."

Potash Mining in Germany and France

Description: From Scope of Bulletin: "This paper is confined largely to a discussion of methods of mining potash salts in France and Germany, in view of the possible application of similar methods when mining of the deposits in the southwestern part if the United States is undertaken, but it also includes a brief history of the German and French potash industry, a discussion of the geology of the deposits, a short description of the refining of crude salts for export, and an estimate of the cost of production."

Stone Dusting or Rock Dusting to Prevent Coal-Dust Explosions, as Practiced in Great Britain and France

Description: From Introduction: "Coal dust as an agent of widespread explosions had been under suspicion, and watering to allay the dust was recommended by some mining engineers but the watering of coal-mine dust was adopted in comparatively few mines of the United States and Great Britain, and had not been introduced widely in any country except Germany. Rock dusting, another method of preventing explosions of coal dust, was early tested with success by the Bureau of Mines in its first gallery at Pittsburgh and, beginning in 1911, at the experimental mine, Bruceton, Pa."
